电位滴定仪是化学分析中的一种工具。这种仪器以往多采用模拟式电路和逻辑器件来控制滴定过程,求取分析结果。近年来,随着半导体技术的发展,大规模集成电路的不断出现,电位滴定装置已开始与微计算机联用。带微计算机的自动电位滴定仪,其主要功能均包含在计算机软件中,故仪器体积小,路线简单,操作功能强,分析速度快,精度高。我们用国产TP—801型单板机与自制电位滴定仪相联,以实现对滴定过程的实时控制和对分析数据的实时处理。 Potentiometric titrators are a tool in chemical analysis. In the past, this type of instrument used analog circuits and logic devices to control the titration process and obtain the analysis results. In recent years, with the development of semiconductor technology, large-scale integrated circuits continue to appear, potentiometric titration device has begun with the microcomputer. Automatic potentiometric titrator with microcomputer, the main functions are included in the computer software, so the instrument is small, simple route, powerful operation, fast analysis, high precision. We use homemade TP-801 single-board machine and homemade potentiometric titrator associated in order to achieve real-time control of the titration process and analysis of real-time data processing.
